Question

The students decided that they would investigate some of the abiotic factors. List 3 water quality tests that could be conducted and explain what information each test provides. Include in you answer description of the impact of each factor on the distribution of aquatic organisms.

1. - Dissolved oxygen test tests the amount of dissolved oxygen.
-impact: required for the use of oxygen (aerobic respiration) decomposition
2. -Ammonia test tests the level of ammonia
-impact: leads to algal blooms
3. -Carbon dioxide test tests the amount of carbon dioxide
-impact: increased CO2 -> decreased pH
decreased CO2 -> decreased photosynthesis

Answer 1

Answer: The three test include, Ammonia test,dissolved oxygen test, carbon dioxide test

Step-by-step explanation:

Ammonia test- this help to test the amount of ammonia available in the aquatic habitat to determine it sustainability of aquatic organism such as algae bloom

Dissolved oxygen test- Oxygen is essential for respiration( aerobic respiration) of animals, the test identify the level of oxygen available to sustain respiration.

Carbon dioxide - carbon dioxide is an essential reactant for photosynthesis, the test determines the amount of carbon dioxide.

Temperature - an increase in temperature increase metabolic activities and organism sensitivity to toxins.

Nutrient - increased nutrients level increase their growth and also determined how organism are distributed in the aquatic habitat.

Carbon dioxide - It influence the pH an increase carbon dioxide decrease pH and increase photosynthesis.
